Abstract: An apparatus for scrambling/descrambling input data to produce output data. A data memory (32) stores a data word, a bit invert flag, and numerical data. A bit shift operating section (4) performs, on receiving a bit of data to be outputted or a bit of input data, a bit shift operation with the bit and stores the resultant data in the data memory (32) in the form of a first data word. A randomizing/derandomizing section (1) randomizes or derandomizes the input data by using the first data word and based on a generating polynomial and, depending on the state represented by the bit invert flag, inverts the bit of the data to be outputted to develop output data. A count processing section (2) increments or decrements the numerical value stored in the data memory (32) and, depending on the numerical value, selectively turns the bit invert flag to a predetermined state. A count controlling section 3 replaces the numerical value with a predetermined initial value on the basis of the first data word and bit invert flag. The data memory (32) holds a second and a third data word (dw0, dw1), bits of which corresponding in position to a particular bit (B8, B9, B12) of the first data word are a ZERO and a ONE, respectively. The count controlling section (3) reads either one of the second and third data words (dw0, dw1) out of the data memory (32) depending on the value of the bit which is inputted to the bit shift operating section (4), Exclusive-ORs the data word (dw0, dw1), first data word, and third data word (dw1), performs a masking operation with a data word (a1) resultant from the Exclusive-ORing for validating a bit corresponding in position to the particular bit position (B8, B9, B12) of the first data word while invalidating the other bits, and replaces the numerical value with the initial value when a data word (a2) resulting from the masking operation is indicative of a ZERO or when the bit invert flag is in the predetermined state.

Abstract: For the purpose of testing optical fibres (12) in conjunction with measuring the optical path length, a device having a modulator (5) outside the light source (1) is proposed which modulates the amplitude of the measuring light beam. Twofold modulation before and after passage of the test fibre (12) using the reflection method with a specific sequence of modulation frequencies yields the characteristic minima of a detection signal, from which the same absolute measurement results are calculated even when measurement is done using different instruments. Furthermore, a modulator is specified which can be implemented using the technology of integrated optics, as is a method making use of the device, which can also be applied to fibres having fibre breakages. <IMAGE>

Abstract: According to an apparatus for and a method of evaluating a multilayer thin film of the present invention, an interference light beam in a predetermined wave number region is projected as a parallel beam onto a multilayer thin film sample (11) and the interference light beam reflected by the sample (11) is detected to find an interferogram. The interferogram is subjected to a Fourier transform, filtering and a reverse Fourier transform so that a spatialgram is provided. Thereby the variation of the incident angle of the light beam impinging on the sample and the incident surface is reduced, and the spatialgram can be provided with accurate information of the multilayer thin film. According to the apparatus and the method of the present invention, the reverse Fourier transform is performed by means of complex power reverse Fourier transform. As a result, compared with the case of performing cosine reverse Fourier transform, more information can be introduced in the same photometrical wave number range and a thin film measuring limit is improved.

Abstract: Apparatus, and accompanying methods for use therein, for translating virtual page addresses in one address space, e.g. virtual, to page addresses in a second address space, e.g. real, and specifically for increasing the speed of such translations by translating multiple contiguous virtual page addresses upon the occurrence of a miss in a translation lookaside buffer (TLB). In response to a TLB miss, the address of each virtual page in a pre-defined block of, e.g. four, contiguous virtual pages, is separately translated through segment and/or page table lookup operations to yield corresponding page frame addresses. The virtual and corresponding page frame addresses for this block are then stored within a single TLB entry. Inasmuch as successive virtual page addresses can be constructed through simple incrementation of a starting virtual page address for this block, a TLB entry contains the first virtual page address for the block followed by the separate page frame address, and its associated invalid and page protection bit fields, for each of the contiguous virtual pages in that block. Since segment and block values are the same for all the page frame addresses in each block, these values are only stored once within the corresponding TLB entry for that block.

Abstract: A sound field switcher inputs an output sound field signal from a sound field producer. The inputted sound field signal is delayed sequentially by plural delayers, after which they are multiplied by coefficients by plural multipliers, and the multiplied results are all added by an adder. Coefficients stored in an area of a memory indicated by a coefficient counter are read out and set to the plural multipliers. The sound field switcher carries out control of the timing for switching the sound field signal produced by the sound field producer and the timing for the coefficient counter to commence counting. Assuming the time required for switching the sound field to be N sampling periods, in case of carrying out a sound field switching from a sound field A to a sound field B, a sound field switching controller issues an order to the coefficient counter so as to count up one by one from 0 to N, and on each count the coefficients stored in an area of the coefficient memory is set to the multipliers. When the count value of the coefficient counter comes to (N/2) or nearest to (N/2), the sound field switching controller issues an order to the sound field producer to output the sound field signal of the sound field B. When the count value of the coefficient counter comes to N, the switching from the sound field A to the sound field B is completed.
